摘　　要：应用有限元模拟软件ANSYS/LS-DYNA对铝合金轮毂拉深旋压成形过程进行三维有限元数值模拟。通过对其成形过程起关键作用的工艺参数(旋轮直径、主轴转速、旋轮进给率、旋轮运动轨迹)的改变,对比不同工艺参数下变形区应力、应变的分布规律及对旋压力和壁厚的影响,揭示不同工艺参数对普通旋压成形影响的规律,优化工艺参数。最后根据模拟结果分析旋压成形过程中出现的缺陷及原因,通过试验验证模拟的可行性。The draw-sprinning forming process of aluminum alloy hub is simulated by the FEM software ANSYS/LSDYNA.Based on the analysis the rule of stress and strain,and comparison the influence on spinning force and wall thickness under different technological parameter(roller diameter,main spindle rotate speed,roller feed and motion trace) then the influence laws of forming process is explained,and the technological parameter can be optimized according to the simulation result.Finally,the reason of all kinds of defe...
